1 Claim.

The invention relates to window sash, and more particularly tofabricated or welded steel sash having a ventilator section.

The object of the invention is to provide certain improvements inso-called basement window sash whereby the ventilator section may beswung to a partially open position, to a full open position and also maybe readily removed from the fixed frame portion of the sash withouthaving to remove bolts or other special fastening means.

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings; Fig. 1 is an elevation of a sash construction embodyingthe invention, parts being broken away and parts being shown in section;

Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 2 showing the ventilator in full openposition;

Fig. 4 is a detail sectional view taken in line 44 of Fig. 2;

Fig. 5 is a detail sectional view taken on the line 55 of Fig. 4;

Fig. 6 is a detail sectional view taken on the line 6-6 of Fig. 1.

Fig. 7 is a detail front elevation view of the window sash embodying theinvention showing lower and upper corners thereof; parts being brokenaway and parts being shown in section;

Fig. 8 is a detail sectional view taken on the line 8-8 of Fig. 7

Fig. 9 is a detail sectional taken along the line 99 and 8.

Referring to the drawings, the numeral 9 designates generally the fixedframe section of the sash and it will be noted that it consists ofangled sections including side T-bar sections 10, top T-bar section 11and bottom channel section 12 which may be welded or otherwise securedto gether at the corners so as to form a frame, the side frame portionhaving angle iron sections 13 also secured thereto to act as a masonguide and also for attaching screens and storm sash to the frame.

The ventilator section 14 is formed by T-bars 15 joined as by welding attheir upper ends to a transverse or top T-bar 15' and at their lowerends to an angle bar 16 which angle bar has one of the legs of a smallerangle bar 17 welded or 7 otherwise suitably secured thereto.

With the above construction, the inwardly proview, the same being asshown in Figs. '7

jecting flanges 18 of the sides of the fixed frame 9 form rails againstwhich the ventilator section abuts when in closed position as shown inFigs. 2, 4 and 8 and the angled bar 17 is notched at 19 to receive theseflanges or rails within the notched portion thereof as shown in Figs. 4and 8 and has a tongue or projection 20 engageable with these rails andprovided with a bevelled end 21 engageable therewith when the ventilatoris swung over to a full open position as shown in full lines in Fig. 3and in dotted lines in Figs. 5 and 9 at which time also it will be notedthat the bases 22 of the angle bars 16 of the ventilator section abutagainst the flanges or rails 18 at a point offset from and on theopposite side of the engagement of the tongues 20 therewith, and thusthe ventilator section may be held in full open position at either thetop or bottom of the fixed frame as shown in dotted and full linepositions respectively in Fig. 3 or said section may be similarly heldin any intermediate position between the top and bottom through theintergagement of the projection 20 and frame members 14 with the railsor flanges 18 when said ventilator section is moved to this position,the Weight of the overhanging frame maintaining this engagement. Becauseof this type of joint construction also it will be noted that, when theventilator section 14 is in open position on the 5 rails 18 and it ispartially tipped to release position relative to said rails so that thetongue projection 20 and bar 16 are not clamped to the rail and then oneend of said frame 14 is tipped vertically out of alinement with theother so that the end so tipped will have its notched portion 19released from its cooperative rail 18, that the opposite notched portion19 of the ventilator 14 may then be disengaged from its rail 18 so thatthe entire ventilator section 14 may be removed from the fixed frame 9without the necessity of removing bolts or other fastening means.

The base portion or bottom channel section 12 of the fixed frame 9 has atransversely extending angled bar 23 secured thereto, one of its legs23' having upturned edges 24, see Figs. 1 to 3,

engaging the angle bar 17 when the ventilator 14 is in closed position,see Fig. 2, and the other leg 25 providing projections 25', see Fig. 9,adjacent the ends of the frame 9, engageable with the notched portions26 of the side frames 15 of the ventilator section 14, when in half openposition as shown in Figs. 2 and 9 in dotted lines and cooperating withthe projections 20, engageable with the flanges 18, to hold theventilator no section 14 in partially or half open position.

It is also to be noted that when the ventilator section 14 is moved tofull open position adjacent the base 23 of the frame 9 that saidventilator 14 will engage the upper edge of the leg 25 as shown in Fig.3 to positively hold the ventilator 14 in open position, said leg 25providing stops for this purpose.

When in closed position, any suitable latch or other fastening means maybe used to secure it in this position and for this purpose I have showna latch lever 27 pivoted at 28 on the top portion of the ventilatorsection and having a cam or locking projection 29 adapted to be turnedinto cooperative looking or latched engagement with a stop or tongue 30stuck out from the top portion of the fixed frame 9, see Figs. 1 and 6.

The window panes are adapted to be mounted in the spaces provided forthem in the ventilator section in the usual manner.

With the above construction it will be noted that when the ventilatorsection is swung partially inwardly relative to the fixed frame thatsaid section may then be moved up or down on the rails or flanges 18 andthen swung to full open position and be there retained either at thetop, bottom or intermediate the fixed frame and that it may also beswung to a partially open position and retained therein.

It will also be noted that when the ventilator section is closed, thesides and top thereof abut against the inwardly extending portions ofthe T-bars of the fixed frame and the depending leg of the angle bar 17abuts against the front face of the channel bar 12 to provide a weatherseal.

I desire it to be understood that this invention is not to be limited toany particular form or arrangement of parts except in so far as suchlimitations are specified in the claim.

What I claim as my invention is:

In a window sash, the combination of fixed sash frame having aventilator opening with inwardly projecting flanges forming side rails,a movable ventilator section adapted to fit within said opening andhaving a bottom portion and side frame portions overlapping the innersides of said side rails and having a depending flange at its bottomoverlapping the lower part of the main frame and provided with lateralextensions overlapping the outer portion of said side rails, and ofisetfrom I the lower ends of said side frame members, said lateralextensions and said side frame portions receiving said rails betweenthem and the bottom portion of said ventilator section cooperating withsaid lateral extensions to clamp said rails between them in any positionof vertical adjustment of said ventilator section to hold saidventilator section in full open position, said side frame portionsabutting the inner side of said side rails for their entire length andsaid depending flange for its entire length abutting the outer side ofthe lower part of said main frame when the ventilator is in closedposition.
